Photos of a SS, b Ni, c Cu, d Al, e Al/C, f Li and g Cu/Li current collectors after contact (undirect contact into vials) with LPSCl electrolyte after 2 months and after 4 h heat treatment at 60 °C. This experiment simulates the contact of LPSCl pellet and current collectors and the possible formation of side reaction components (impurity phases of Li2S, LiCl, and/or Li3PO4) into vials which are quite toxic and aggressive to current collectors and lithium metal anode sources.
